To investigate whether a slimming diet based on alternating (low with normal) energy intakes could counteract a decrease in energy requirement, 24-h energy expenditure (24EE), sleeping energy expenditure (sleeping EE), and physical activity were determined in a respiration chamber in 27 overweight women: before weight reduction and after 4 and 8 wk of slimming. Daily alternating and continuous slimming diets were supplied. Average weight losses over 8 wk of slimming were 6.9-9.0 kg. After 8 wk at low energy intake, 24EE had declined by 12-16% (from 2328 +/- 219 to 1987 +/- 204 kcal, mean +/- SD). Sleeping EE had declined by 7-13% (from 64 +/- 6 to 57 +/- 6 kcal/h). Measurements of physical activity indicated a reduction of spontaneous physical activity during slimming. Alternating low energy intake did not prevent 24EE from declining. The reduction in 24EE was determined by a decrease of body weight, dietary induced thermogenesis (in proportion to caloric restriction), and physical activity. There seems little reason to consider other adaptive mechanisms.
为了研究基于交替（低能量与正常能量）摄入的减肥饮食是否能抵消能量需求的下降，我们在呼吸室内对27名超重女性进行了24小时能量消耗（24EE）、睡眠能量消耗（睡眠EE）和身体活动的测定：在减肥前以及减肥4周和8周后。提供了每日交替和持续的减肥饮食。8周减肥期间的平均体重减轻为6.9 - 9.0千克。在低能量摄入8周后，24EE下降了12 - 16%（从2328±219千卡降至1987±204千卡，平均值±标准差）。睡眠EE下降了7 - 13%（从64±6千卡/小时降至57±6千卡/小时）。身体活动测量表明减肥期间自发身体活动减少。交替低能量摄入并不能阻止24EE下降。24EE的下降是由体重减轻、饮食诱导产热（与热量限制成比例）和身体活动减少所决定的。似乎没有什么理由考虑其他适应性机制。
